How this service works
Pay-per-call data & tool APIs
Output
A JSON object with metadata (run time in ms, settlement status, item count) and a results array. Each result includes: whether the wallet was found, the wallet address, chain ID, a human-readable summary, ETH and native token balance, count of large native movements (≥1 ETH), up to 20 recent token transfers (with timestamp, amount, direction, token symbol), large movement details (timestamp, tx hash, value in ETH, direction, counterparty address), source coverage status for balance/token/native queries, and any source errors.
Example use cases
Whale wallet movement alert
“Check the Ethereum wallet 0x28C6c06298d514Db089934071355E5743bf21d60 and tell me if it has made any large ETH movements recently — anything 100 ETH or more — and what tokens it has been transferring.”
DeFi portfolio surveillance
“I need to keep an eye on this suspected whale address 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 on Ethereum — can you pull its current ETH balance and show me its recent outbound token transfers?”
Suspicious wallet audit
“Someone shared a wallet address 0xAb5801a7D398351b8bE11C439e05C5B3259aeC9B with me — can you check if it's been moving large amounts of ETH or tokens on chain recently?”
Technical details
Endpoint
POSThttps://api.timzinin.com/api/whale-wallet-trackerWhen to prefer
Choose this endpoint when you need a quick, pay-per-call on-chain snapshot of a specific Ethereum wallet — especially for whale tracking use cases where ETH balance, large native movements, and recent token transfers are all needed in a single call. Prefer this over block explorer APIs when you want structured JSON output with pre-filtered large-movement detection rather than raw transaction lists.
Side effects
- Wallet address not found or invalid — returns found: false
- RPC or data source errors surfaced in sourceErrors fields (balance, tokenTx, nativeTx)
- Chain ID not supported — no results returned
- Malformed wallet address — API-level error or empty results
- Network timeout — run_ms elevated, partial data possible
- Payment not settled — x402 payment required before data is returned
